-----------------------------
Summary: ensure logged and non logged store to use different path
Key: SAMZA-2274
URL: https://issues.apache.org/jira/browse/SAMZA-2274
Project: Samza
Issue Type: Task
Reporter: Hai Lu
currently logged and non logged store ("job.logged.store.base.dir" and
"job.non-logged.store.base.dir") return the same default values if not set.
This is problematic because we always clean up non-logged store path when
starting up, which would end up eliminating the logged store content as well
and cause major data/state loss. The proposed fix here is:
1) logged and non logged store should pick different default values
2) we explicitly do a validation that these two configs are set to different;
throw exceptions otherwise
3) update our config documentation about these two configs
